 New Comment:

I wouldn't want to have it included in the interface as the implementation between both is
different. Datetime returns itself, while DateTimeImmutable returns a new instance of
Datetimeimmutable. So technically the return value is not the same…

Sorry, I meant:

Both of DateTime and DateTimeImmutable expose add method. As "DateTimeInterface is
meant so that both DateTime and DateTimeImmutable can be type hinted for", why it does not
include add method?
